Description
Die vorliegende Erfindung betrifft eine Beleuchtungsvorrichtung für ein Kraftfahrzeug, insbesondere in Form einer Leuchte in einer Rückblickvorrichtung, nach dem Oberbegriff von Anspruch 1. Sie bezieht sich auch auf eine Rückblickvorrichtung mit einer solchen Beleuchtungsvorrichtung.The present invention relates to a lighting device for a motor vehicle, in particular in the form of a lamp in a rear-view device, according to the preamble of
Der Begriff „Rückblick“ ist hier als eine Sicht auf den umgebenden Bereich definiert, der nicht im Blickfeld eines Fahrers eines Fahrzeugs liegt, d.h., die Richtungen entgegengesetzt, links, rechts, unterhalb und oberhalb der Blickrichtung, kann aber auch die Sicht in Richtung der Blickrichtung des Fahrers und/oder beliebige Kombinationen der Richtungen umfassen. Der Rückblick kann über ein reflektierendes Element wie einen Spiegel und/oder eine Bilderfassungseinrichtung wie eine Kamera erreicht werden.The term "rear view" is defined here as a view of the surrounding area that is not in the field of vision of a driver of a vehicle, i.e., the directions opposite, left, right, below and above the line of sight, but may also include the view in the direction of the driver's line of sight and/or any combination of the directions. The rear view may be achieved via a reflective element such as a mirror and/or an image capture device such as a camera.

Die Lichtübertragungseinheit 30 ist als zweiteiliges Bauteil, nämlich in Form eines Spritzgussteils, vorgesehen, wobei das Gehäuse 32 neben der Lagerung und dem Schutz der Lichtquelleneinheit 10 sowie der Lichtleiteinheit 20 innerhalb einer nicht gezeigten Rückblickvorrichtung eines Fahrzeugs einschließlich Befestigung an der Rückblickvorrichtung eine Vielzahl von Funktionen erfüllt. Das Gehäuse 32 wirkt auch als eine Blende, die einen Bereich definiert, der neben dem Fahrzeug beleuchtet ist. Ferner ist es mit Verstärkungsrippen 34, umfassend insbesondere Ränder, und Befestigungsmitteln 33 für die Lichtquelleneinheit 10 und die Lichtleiteinheit 20 versehen. Weiterhin gewährleistet das Gehäuse 32 eine hohe Wärmeabfuhr weg von der Lichtquelleneinheit 10, indem es aus einem Material mit einer hohen Wärmeleitfähigkeit ausgebildet ist.The
Jede der LEDs 11, 12, 13 ist mit einem der Trichter 21, 22, 23 in einer Eins-zu-Eins-Assoziation assoziiert, sodass von den LEDs 11, 12, 13 emittiertes Licht innerhalb der Lichttrichter 21, 22, 23 geführt wird, um im Bereich des als eine Linse wirkenden Lichtfensters 31 gebündelt zu werden und somit einer homogenen Beleuchtung des fahrzeugnahen Bereichs zu dienen. Zu diesem Zweck ist die optische Achse, welche von jedem der von den LEDs 11, 12, 13 emittierten Lichtbündel bereitgestellt wird, zur horizontalen Ebene geneigt. Wie in

Mithilfe von Rückblickvorrichtungen, darunter insbesondere Kameras, können unterschiedliche Funktionen und Vorrichtungen eingebaut und/oder gesteuert werden. Zur Verbesserung der Sichtbarkeit ist eine Beleuchtung über eine erfindungsgemäße Beleuchtungsvorrichtung insbesondere bei der Verwendung von Kameras hilfreich.With the help of rear-view devices, including in particular cameras, different functions and devices can be installed and/or controlled. To improve visibility, lighting via a lighting device according to the invention is particularly helpful when using cameras.
